Detailed Summary

This phase I trial studies the side effects of OBP-301 when given together with carboplatin, paclitaxel, and radiation therapy in treating patients with esophageal or gastroesophageal cancer that invades local or regional structures. OBP-301 is a virus that has been designed to infect and destroy tumor cells (although there is a small risk that it can also infect normal cells). Chemotherapy drugs, such as carboplatin and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving OBP-301 with chemotherapy and radiation therapy may work better than standard chemotherapy and radiation therapy in treating patients with esophageal or gastroesophageal cancer.

Arms & Interventions

Treatment (OBP-301, carboplatin, paclitaxel, radiation)experimental

Patients receive OBP-301 (1×10\^12 vp/mL) by intra-tumoral injection via endoscopy on days -3, 12, and 26. Patients also receive paclitaxel IV (50 mg/m\^2) over 60 minutes followed by carboplatin IV (AUC 2) over 30 minutes and on days 1, 8, 15, 22, and 29, and undergo radiation therapy (1.8 Gy/faction) on Monday through Friday beginning day 1 for 28 fractions (50.4 Gy total) over 5.5 weeks. All treatment continues in the absence of disease progression or unacceptable toxicity.
